DGAF is an acronym for dont give a fuck. It is basically what immature lifted truck driving pot smoking douche bags call a lifestyle. They claim that it means not caring what people think and living life how they want to. Thats fine but no one really cares that they want to drink coors light, smoke pot, and wear socal shirts.

Something insecure people use when a lot of fucked up shit happens to them, as a way to cope with/disguise their pain. Also something a lot of chongas use as their last name on Facebook.
"Hey man your a one-armed orphan and you were just diagnosed with tuberculosis and your girlfriend cheated on you with your dead puppies corpse. You never graduated high school and you live in a garbage can behind the supermarket where you suck dick for breadcrumbs, rolled in semen. And your deaf in one ear. Just sayin."
